TRUNK-Loox. i

To all whom may concern Be it known that? I, JOZEF DnMBIozAK, a "subject ofthe Emperor of Austria,-fresid ing at Wallingford,v in the-county o'f-New 'Haven and kState of Connecticuahaveinkvented certain newyands' useful Improve 'ments in Trunk-Lockaof which; the following is a specih'zation.-v

This invention' relates 'to'locks` and has special reference toa'trunkflock such asis used on "trunksy `andboxes wherein the top v`is yhinged to the @body of the trunk` andthe free'edge of the hinged top is locked to the front: of the body'.y The dev ice'may also' be used in Connection with' 'any articlesof this sort'suchas chests and satchelsg' "i In vordinary'constructioli' of"I trunks and the like, it is' customary to-*fput a lock, fusually with a-"hasp, in the center; of the front of the chest orftrunk-A and near eachcornell 1fof" the'front there' is an` additional'.`latch.

Thus 'to'lock the' trunk requires three operations, 4first 'thetrunkf'lis `closed and lthe 'latches are successively thrown andfinally '2 5 the hasp'is yclosed' andlocked -in closed posi- .tion."V14 l f Oney important object of thejinvention is Lto provide' animproved and simplied con- 'structionfordevices of this 'character where- A in the latching of=ea`ch endof the topiwill be accomplished by Ithe act of closing the yIii' is a w'ell'know'n fact that most' of the locks'used on trunks are capablelof 'being picked with aconsi'derable degree of facility since the keys are usually of a very simple character. l f f A=second important object of the inven- -tion is vto provide an improved and novel Y 40 lconstruction of lock wherein, even though the llock bepicked so that the hasp can'open, further manipulation will *be required to' disengage the latch members adjacent the cor- Vners of the trunk, the manner ofthe manip- Y A t ulation" being :hiddenso thata'person not 1knowing 'the method-of "opening the trunk will experiencea' very considerable V'degree f of ditliculty. in manipulating the 'device even after the hasphas been unlocked; Y "With theabove and other objects in view, i 'as will be hereinafter apparent the `invention `consists in general offcertain novel de- 'tailsof construction and combinations' of parts hereinafter fully described, illustrated in the accompanying drawing, and' specifiy Spmiifcaton of Letters Patent. ApplicationxIe'dJuI-y 17, 1918. Serial No. 245,379.

This bolt is held from vertical movement by onefor more tumblers 20 of the usual key" operated type, it not being neces,-

sary to go into a detail'description of this 'feature of the device as any desired form of key' control may' be used to prevent vertical'movement of-thef `bolt 16 Without the luse ofy the proper key'.r The, upper i end" of the bolt`16 'is provided'witha slot 21 wherein are located pivotally mounted. tumblersl 22 'which arefso larranged,thatwhen thebolt is raised upward the flower y'ends' of, these tumblersf fengage against' the underside yof .the flange 1 1 f and thrust'the upper ends lof the tumbler-s outward asshown inl Fig. 2.y
